DES MOINES, Iowa — Michele Bachmann served up red meat to the crowd at the Iowa conservative principles conference Saturday, slamming President Barack Obama as a Jimmy Carter retread, dissing the Mitch Daniels “truce” call for social issues, and saying she wants a “waiver” from the last two years of White House leadership.

Talking loudly and waving her hands, a pumped Bachmann used a slide presentation of various numbers — the national debt, the cost of a gallon of gas two years ago the day before Obama took office, the corporate tax rate — to make her points and pull the crowd in.
