Its called GETTING ELECTED!
I've watched dozens of elections and this is how it works. Politicians tell their supporters what they want to hear and tell lies to their opponents...They are all the same Republicans, Democrats, Labour, Conservative, even Scottish Nationalist(very infrequently).

Don't get excited Alice, I think you will find that when elected these politicians stop lying and continue to behave just as they did before the election, all looking after the interests of the rich(and their own) at the expense of the poor.
It is common for partisan supporters of either of the parties to lose all sense of reason or judgement and start throwing stones and dodgy videos around.

When the disorder reaches this stage, chances of recovery are said to be poor..
