1) He introduces himself as the "champion of the constitution", yet he wants to repeal the 14th amendment right of people born in the USA to be a citizen. Because of that position I think he is a racist bigot. It's not too hard to figure out who he is targeting with that salvo at the Constitution.

2) He has approximately zero experience as an executive, yet he wants to hold the most important executive position in the country. I think it's a little bit late for an old dog like him to be learning new tricks.

3) Most of his supporters are extremely annoying, and most of his critics are extremely annoying.

4) Voted to impeach Clinton

5) He will not win.

But to be fair, we should not only look at the "what is wrong with Ron Paul". We also need to weigh in "what is right with Ron Paul" too.

1) He's against the war on drugs, somthing he could end on the federal level on day one in office.

2) Recognizes the right to life.

3) Vehemently anti-socialist.

4) He's not Rudy Giulianni

5) He advocates smaller government.
