Text, tweet, win? Not so fast.

[Commentary] President Obama's 2008 campaign showed how the Internet could be used to organize grass-roots supporters into a nationwide political force. Now House, Senate and gubernatorial candidates across the country are finding it isn't so easy to duplicate Obama's results. To show that they "get" the Web, too, politicians are venturing online to raise money, organize volunteers and communicate directly with supporters. They rack up Facebook friends, tweet their every thought and action (or assign some poor young staffer to do it for them), shell out for Obama-style iPhone applications and wait for the Web to work its magic. A lot of them have been disappointed to find that all that motion doesn't necessarily translate into votes.
