From the folks over at Politico:
With speculation growing that he’ll join the wide-open 2012 Republican presidential field, South Dakota Sen. John Thune plans to roll out a sweeping proposal Tuesday to remake the congressional budget process.
Thune’s budget plan would create a joint House-Senate panel on cutting government spending, call for a line-item veto and mandate that 10 percent of the deficit be cut each year until it is eliminated.
As he tries to build up his policy credentials, Thune is also stepping up his political travel, headlining a Republican Party of Virginia event on Wednesday, to be followed by trips to Arkansas, California and Ohio on behalf of GOP Senate candidates. With Thune in heavy demand on the campaign circuit, more such trips are expected soon.
Then there is this little bit from near the end of the article:
Thune would be in a strong position if he wants to make a White House run. Handsome, articulate and very popular among conservatives and evangelical Christians, Thune is unopposed in his bid for a second Senate term, an unprecedented position for any Senate candidate in South Dakota history.
