Issue bugs I've noticed

First, Republican voters are +21 in support of affirmative action (the same as Democratic voters); I assume that's a typo.

Second, shouldn't custom candidates start out with the default issue positions of their political party unless I change it when customizing?  It seems strange to start custom candidates out with a +5 on every issue; the 100 points you are given to change positions are not enough to change many issues.

Third, I've noticed that sometimes when I go on a tv interview program, my opponent's issue ratings go down dramatically.  Once, I noticed that my opponent's improve-the-economy score went from +40 to +6 in every state after I went on the tv show.  Is that supposed to happen?
