The CNBC All-America Economic Survey of 800 people across the country conducted by Hart-McInturff, finds that, in general, Americans oppose defunding Obamacare by a plurality of 44 percent to 38 percent. Opposition to defunding increases sharply when the issue of shutting down the government and defaulting is included. In that case, Americans oppose defunding 59 percent to 19 percent, with 18 percent of respondents unsure. The final 4 percent is a group of people who want to defund Obamacare, but become unsure when asked if they still hold that view if it means shutting down the government.

Once again, the American people have spoken. Defunding Obamacare is not what they want. But even the minority who does want it think shutting down government or defaulting on the national debt to do so is a bad idea Even most Republicans, who support defunding Obamacare by a 51 percent margin, oppose doing so through a government shutdown or default, 48 percent to the 36 percent who support it. Three guesses who the 36 percent is. Yep, teabaggers, "the only demographic measured in the poll with such a majority." Does that sound familiar? It should, it's what Pew Research found last week.

So a tiny sliver of the voting population, who are critical to Ted Cruz's 2016 plans, are driving Republicans over the cliff. And taking the rest of the country with them.

Stand with Daily Kos and the Democratic Senatorial Campaign Committee in denouncing Republicans who would completely shut down the government just to destroy Obamacare.
