I can see how he hijacked it. He let too many people get away, Winning the presidency is not hijacking a party. Too many powerful old-time republicans sabotaging him.
I only cry myself to sleep when I think of all the idiots who are republicans, not conservative.
Two things to keep in mind before you complain about the GOP failing to support Trump and failing to help push his agenda:
1. From what I've read, every GOP House and Senate member who won in 2016 carried his/her district or state by a larger margin than Trump did. Keep this in mind when you wonder why these people aren't enthusiastic Trump supporters. Their constituents like them more than they like Trump.
2. Trump held a rally in Grand Rapids, Michigan a couple of months ago. According to the accounts I've read, somewhere between 30% and 35% of the attendees were registered Democrats. These are voters who will vote for Trump but are not likely to vote for GOP House and Senate candidates.
What Trump is doing here is trying to steer a political conversation within a two-party system when our political landscape is actually dominated by three political movements:
A. Globalism (the dominant movement in Washington ... Hillary Clinton was the Globalist candidate in 2016)
B. Marxism (a subset of the Democratic Party ... Bernie Sanders was the Marxist candidate in 2016)
C. Nationalism (a loosely-affiliated group of mostly Republicans but also many Democrats and conservative Independents ... Donald Trump was the Nationalist candidate in 2016)
Here are your three "political parties," folks. Now tell me how Party C wins control of anything beyond the White House.
