Republicans are in a lose-lose situation. [View all]
There are currently two possibilities for the Republicans in regards to the presidential primary.
1.Trump gets over 50% of the delegates and there is no brokered convention. They then have the candidate who has the highest unfavorability rating of all time at the top of their ticket. Therefore, their odds of winning are low.
2.Trump does not get 50% percent of the delegates, but still wins a plurality, but not majority. There is a brokered convention and the party insiders choose someone they think is more electable. Donald Trump gets mad, either runs third party or tells people not to vote for the Republican. He will say the party insiders screwed him over, despite the fact that he got more votes than any other candidate. There is a major rift in the Republican party, making it very hard for them to win.
I don't know which of these two things will happen, but both of these options aren't good for them. I don't really see how Republicans can win this year, regardless of if there is a brokered convention this year or not.
