How do you think they got those in the first place though?
Oh, and massive organization of voters and rabid progressive populist support.
President Trump, above all, is the clearest and most direct example of how you absolutely can get what you vote for in the US. Republicans did not want Trump and fought it as much as they could. They openly declared how bad he was and how stupid and how awful he would be, and it didn't matter. Because people voted.
Donald Trump is in flagrant violation of constitutional law constantly, again, and it doesn't matter because voters want it.
He should be in prison but it doesn't matter because voters wanted him, wanted his bullshit, and voted against anyone who got in their way.
And yet, losers will STILL insist that "voting doesn't matter" or "Blah blah money in politics"
All you gotta do is vote people.
