Those who don't think Obama would be so bad should try living in Chicago for a little while. You can't legally own a handgun. Carrying a loaded handgun is a felony anywhere in the state. All guns must be registered under a system designed to be frustrating to navigate and reregistered every year. If you miss the deadline for re-registration once, your gun becomes forever unregisterable. No magazines over 10 rounds, no carbines with the mag well in the pistol grip, no evil black rifles, no mini-14's (county ban, not city), no semi-auto shotguns that can hold over 5 rounds, and the list goes on. That's what he thinks "common sense" restrictions are. And the kids here keep killing each other with these guns that were banned before they were born.
When he was a state senator, he had ample opportunity to do something about it, but instead chose to vote for more restrictions, remain silent while his mentor Emil Jones sent most pro gun legislation to die in committee and stood by his ally, mayor Daley, while he ranted and continues to rant about these guns that are causing all the violence in his great city. If he can't see the folly in that, how can he lead a nation?
Those who think his policies will be better for the economy are fooling themselves as well. Increasing taxes on the people who invest, hire and take risks does not encourage any of those activities. Raising the bar on their contributions to health care will cause them to think twice about adding someone else to the payroll. Additional trade restrictions will limit our ability to profit from industries where we have a competitive advantage and cause us to expend efforts in industries where we don't. Removing the right to have a secret ballot in unionizing will open the door to heavy handed tactics from those who would take advantage of members rather than working for them.
McCain isn't who I had hoped for, but for those projecting their idealized notions of what Obama's "hope" and "change" mean, be prepared to be disappointed when your free pony (or whatever he's pushing nowadays) doesn't arrive on time if he gets elected.
