Are Long, Drawn Out Campaigns Pointless? [Poll]

It's impossible to turn on the TV and not see an attack ad for this candidate, a inspirational ad from that candidate, and soon lawn signs will be popping up like dandelions on your summer landscape. But here's what I'm wondering, is it all pointless?

What I mean by that is, if you plan to vote in November, can you be influenced between now and then, or is your mind pretty much made up at this point? Over the next 5 1/2 months we'll have debates, more ads, more debates, and on and on.

So let us know what you think; is your mind made up this far in advance, or might your mind be changed between now and then depending on what the candidates say and/or do?
