The fact that two large sports arenas were packed to the rafters last night as the DNC met in Chicago still and Harris/Walz had an event in Wisconsin (at the place where the GOP convention was held last month). Last night Trump addressed a group at the Livingston County Sheriff's Office facility in Howell, Michigan.

Although access to the event venue — a warehouse-like facility operated by the sheriff’s office — was limited to a few dozen supporters, dozens more Trump followers made sure to show up in the surrounding neighborhood.

The difference in crowd size (that Barack Obama rightly gave a nod to as one of Trump's major interests) was significant.

Here is a bit of history from Heather Cox Richardson's "Letters From An American" newsletter today, giving context to what is going on in current US politics:

Obama emphasized Americans’ shared values and pushed back against “those who are preparing to divide us, the spin masters and negative ad peddlers who embrace the politics of anything goes.” He reached back into history to prove that “the bedrock of this nation” is “the belief that there are better days ahead.” He called that belief “[t]he audacity of hope.”

Almost exactly twenty years after his 2004 speech, the same man, now a former president who served for eight years, spoke at tonight’s Democratic National Convention. But the past two decades have challenged his vision.

When voters put Obama into the White House in 2008, Republicans set out to make sure they couldn’t govern. Mitch McConnell (R–KY) became Senate minority leader in 2007 and, using the filibuster, stopped most Democratic measures by requiring 60 votes to move anything to a vote.

In 2010 the Supreme Court handed down the Citizens United v. Federal Election Commission decision, declaring that corporations and other outside groups could spend as much money as they wanted on elections. Citizens United increased Republican seats in legislative bodies, and in the 2010 midterm elections, Republicans packed state legislatures with their own candidates in time to be in charge of redistricting their states after the 2010 census. Republicans controlled the key states of Florida, Wisconsin, North Carolina, Ohio, and Michigan, as well as other, smaller states, and after the election, they used precise computer models to win previously Democratic House seats.

In the 2012 election, Democrats won the White House decisively, the Senate easily, and a majority of 1.4 million votes for House candidates. Yet Republicans came away with a thirty-three-seat majority in the House of Representatives. And then, with the 2013 Shelby County v. Holder decision, the Supreme Court gutted the Voting Rights Act, making it harder to protect Democratic voters.

As the Republicans skewed the mechanics of government to favor themselves, their candidates no longer had to worry they would lose general elections but did have to worry about losing primaries to more extreme challengers. So they swung farther and farther to the right, demonizing the Democrats until finally those who remain Republicans have given up on democracy altogether.

Michelle Obama made it clear that we see what the GOP is trying to do and need to work to fix things.

And then Mrs. Obama took up the mantle of her mother, warning that demonizing others and taking away their rights, “only makes us small.” It “demeans and cheapens our politics. It only serves to further discourage good, big-hearted people from wanting to get involved at all. America, our parents taught us better than that.”

It is “up to us to be the solution that we seek.” she said. She urged people to “be the antidote to the darkness and division.” “[W]hether you’re Democrat, Republican, Independent, or none of the above,” she said, “this is our time to stand up for what we know. In our hearts is right. Not just for our basic freedoms, but for decency and humanity, for basic respect. Dignity and empathy. For the values at the very foundation of this democracy.”

“Don’t just sit around and complain. Do something.”

Between the two of them they washed the floor with Trump and his ilk. Getting a good turnout is essential to fixing some of this stuff because the GOP purging voter rolls, the gerrymandering, and the stuffing of courts is going to make it harder as time passes.
