FormerSanDiegan is pretty spot on. This is not an issue related to Republican vs. Democrat at all. To group it as such is short-minded and just wrong. Plenty of people on both sides have engaged in these acts and I know plenty of people who claim to be “Democrats” who, when it comes to themselves, are just as greedy & selfish as any Republican.
For the record I consider myself a republican (although not a Christian Coalition Repbulican at all) and am a responsible adult with no debt and lives well below my means.
