Lefties like to swear they'll leave the country if this or that Republican wins office. It's all like trendy, and stuff. They did it when Bush was running, and they're doing it now. Of course, they never do, because matching action to rhetoric isn't like all cool, and stuff.
Bush is Einstein compared to Trump. Anyone thinking of voting for Trump should be IQ tested before they're allowed into the voting booth. Seriously Trump is full of his own self-importance, knows zip about diplomacy and needs to get rid of that stupid hat and fake tan!
who do you think is qualified... and why?
As someone who supports Hillary Clinton I hope they pick Trump! However the GOP need to get in the real world and pick someone who can reach out to more voters and not alienate the Latino population. To be frank the GOP need to look at demographics and realize that their core vote is shrinking, if they don't win back Latino voters then they have no chance of winning the WH.
In terms of who would give most trouble to Hillary Clinton that would be Jeb Bush, many will say that the Bush brand has been toxified however Clinton to a degree will suffer the same problems. This makes a pretty level playing field, Bush firstly is seen as more intelligent than his brother, more moderate, his Mexican wife and fluent Spanish would help him with the Latino vote but the problem remains your early primaries which push candidates too far too the right.
Those early primaries give too much weight to sections of voters who are obsessed with single issues, theres a lot of shouting and extreme rhetoric, moderate Reps get pushed into positions and then are boxed in.
I'm still learning more about other GOP candidates, Fiorina, Cruz, Carson have no chance, Kasich looks a bit more interesting, Rubio might be okay as VP pick but there could be problems in terms of electoral college if he was VP candidate to Bush. It could be that the Kasich/Rubio combo might appeal, help with the Ohio/Florida states.
Still learning more about the others, as I've said before your elections are much more interesting than ours in the UK. I love election night in the USA, never miss it!
