The Democrats, rather than seize an opportunity to show how identity is irrelevant to success, have decided to make identity politics the centerpiece of their campaign.

During his remarks to the Democratic National Convention, U.S. Rep. Jared Polis, D-Colo., castigated Republicans for mocking “our desire to heal the planet.” Republican presidential nominee Mitt Romney had said during the Republican National Convention that “President Obama promised to begin to slow the rise of the oceans and heal the planet. My promise is to help you and your family.”

Flashback to 2009, when U.S. Rep. Jared Polis, D-Colo., and U.S. Rep. Martin Heinrich, D-N.M. celebrated all those green jobs created in New Mexico. What’s happened since then?

In swing-state Colorado, where a recent Rasmussen poll of likely voters showed Pres. Obama tied with Gov. Romney, discretion might be the better part of valor for Democratic candidates who want to keep, or win, a seat in Congress.

U.S. Rep. Jared Polis, D-Colo., and U.S. Rep. Donna Edwards, D-Md., make some rather astonishing claims about the effectiveness of the Democrats’ stimulus package when addressing the faithful at Netroots Nation 2011.

Maybe it’s time for U.S. Rep. Jared Polis, D-Colo., to update his talking points on the environment. After all, if he’s vulnerable in the general election, it’s going to be in part because of outdated positions like these.

The position taken by U.S. Rep. Jared Polis, D-Colo., to end a federal research subsidy for oil-shale development should prompt him to withdraw subsidy support for other economically uncompetitive energy sources that drive up consumer costs.
