Secondly, it is absolutely ridiculous to state that most Democrats are communists. That word means absolutely nothing now that the vast majority of the people that use it think that "communist" means "anyone who disagrees with me politically". Frankly, at this point you may as well be using the terms "boogeyman" or "Keyser Soze"; you'd have just as much credibility. Ditto with the statement that "Democrats love terrorists". Almost every mainstream conservative American has a friend or relative who is a Democrat, and when some extremist nut comes along to tell them that their frat buddy or Aunt Edna loves terrorists, they aren't going to fall all over themselves to support that person. Making ANY of these statements is political suicide, because most people see that kind of posturing as the vapid "My political party is a football team - Repubs Rool Democrats Drool!" immaturity that it is.
There are many, many reasons to disapprove of the Democratic Party and what it is doing to this country. Focus on them, and lay off the ridiculous ad hominem.
