Does Trump help the republican brand or help expose the republican brand?

He doesn't help it, he hurts it. At least what's left of it. The 25 to 35% of Republicans who support Trump are the Archie Bunkers of the United States. He offered them exposure, they happily grabbed onto it. The rest of the country watches in half amusement/half horror.

Trump is saying out loud, what we are all thinking and don't say. I didn't like his comments about Megan Kelly, that turned me off, but he is most of us. He is saying and displaying every thing that we are all wanting. This is going to be an angry election. We are sick and tired of the lies and scandals by these brain damaged career politicians. I for one, can't stand it any more. He will certainly get things done.

Actually he exposes the Tea party. There are some republicans who are a bit more tactful and who have more common sense.

He ain't no Republican.

He's basically the monster they've created.

They've been keeping their base from reality for years.

The Donald is hurting The Donald. LOL

If you're looking for fat people using oxygen tanks to make fun of head on over to the nearest Bernie Sanders rally.

He is showing how easy it is to lead unintelligent people around by the nose. Like they really believe he could do all the stupid stuff he said.

And they believe because he keeps saying it and telling them they love him.

certainly doesn't help the GOP hates him
