President Obama, beginning a bus tour in Iowa, sought to use Ryanâ€™s seven terms in the House to lash the Republican ticket to dysfunction in Congress. In North Carolina, Vice President Biden deepened an assault on the GOP ticket over Ryanâ€™s proposal to slash the federal budget and overhaul Medicare.
The Romney campaign tested Ryanâ€™s ability to carry its message of a revived private sector, giving him the weighty task of going head to head against Obama in Iowa â€” a state the Democrat won four years ago.
And the Republican team gave a glimpse of how it hopes to deploy the 42-year-old: as an energetic charmer at ease campaigning in his native Midwest. On Monday, he took the spotlight in front of thousands at the Iowa State Fair in Des Moines. Far from playing the part of a conservative ideologue, as some have predicted, he avoided any mention of his signature effort to reform domestic entitlement programs. But he was heckled by protesters over his budget plans nonetheless, quickly transforming his first solo appearance as a national candidate into a chaotic spectacle.
With all four candidates on the two tickets hitting the trail simultaneously for the first time, new polls showed the necessity for both parties to quickly define Ryan. The numbers suggested that, despite his years on Capitol Hill, the congressman remains unknown to many Americans.
AÂ new Washington Post-ABC News surveyreleased Monday showed that positive views of Ryan increased by 15 percentage points after Romney named him to the ticket Saturday. But it also indicated that by Sunday, 30Â percent of respondents still registered no opinion of the congressman.
A newÂ USA Today/Gallup pollÂ found that 39Â percent of Americans thought Ryan was an â€œexcellentâ€ or â€œpretty goodâ€ pick for a running mate â€” but 42Â percent said he was a â€œfairâ€ or â€œpoorâ€ choice.
Obama blamed the Republican Party, including Ryan, for inaction on an issue important to many Iowans: the renewal of the farm bill. Congress had left for its August recess without approving new aid for farmers struggling amid a devastating drought.
â€œI am told that Governor Romneyâ€™s new running mate, Paul Ryan, might be around Iowa the next few days,â€ the president told thousands at Bayliss Park, a square in downtown Council Bluffs. â€œSo if you happen to see Congressman Ryan, tell him how important this farm bill is in our rural communities. Weâ€™ve got to put politics aside and do the right thing for rural America and for Iowa.â€
