According to a poll released Thursday from Investors Business Daily and TIPP, twenty percent of Democrats now oppose Obamacare, and over one in six want to see President Obama’s signature program repealed completely. A whopping 55 percent of Americans are against the law, the highest number charted by IBD/TIPP since the inception of the poll question. Obamacare earns only 37 percent support. Support for repeal of the law has increased four points among Democrats over the last month alone.

Obama’s ratings in the IBD/TIPP Presidential Leadership Index now stand below George W. Bush’s in the aftermath of Hurricane Katrina. That’s driven largely by fear about Obamacare, given that almost four in ten Americans believe they will lose their doctors thanks to the law.
