A patriot is someone who (in his own mind) takes pride in his nation and defends it. This can include people who disagree totally about their country's politics and who recommend completely opposite ways of dealing with problems. ;-D And they will quite likely accuse one another of being "unpatriotic" if that is the case...

Virtually all people are natural patriots to the country they were born in. It's instinctive in people to be that way. They will rationalize their patriotism according to their own self-interest, of course, and that's why things tend to get a little complex when things like money enter the equation.
