On Wednesday, NBC News and the Wall Street Journal released a poll conducted July 18-22, of registered voters nationwide. In a choice between President Obama and Gov. Mitt Romney, respondents favored the President 49% to 43%. Additionally, if the election were held today, swing state voters favor the president 49% to 41%.

The poll shows negative campaigning has affected both candidates as each has seen a rise in the number of respondents who view them negatively. According to the Washington Post, 75-90% of all ads aired across the country in the month of June were negative in nature. The poll is facing a bit of scrutiny; however, including from NBC’s Chuck Todd, that it may be skewed as 46% of participants self-identified as democrats while only 35% self-identified as republicans.

Additionally, the Commission on Presidential Debates announced details on Wednesday for the three 2012 Presidential debates as well as one Vice Presidential debate. The first and final Presidential debates will focus on domestic policy hosted by a single moderator, while the second debate will be a town hall meeting with undecided voters questioning the candidates. Moderators will be announced in August. More details can be found at the COPD website.

Other notes from the trail:

• ABC News has compiled a couple of charts showing how both Presidential campaigns are spending money. The figures include things like rent, credit card fees and payroll.

• The battle for the U.S. Senate in Massachusetts could potentially become the most expensive in history for a senate seat. Scott Brown (R) and Elizabeth Warren (D) have raised a combined $46 million dollars through the end of June, not including money spent on advertising by outside groups. The record currently belongs to the 2000 New York race between now Secretary of State Hillary Clinton and Former Rep. Rick Lazio. Clinton and Lazio spent a combined $70 million in that contest. Recent polls show Warren has a 2 point edge over Brown.

• Congressman Jim Renacci (R) has returned $100,000 in campaign donations amid allegations that the funds were improperly funneled through Canton area businessman Benjamin Suarez. Renacci’s campaign had initially planned to keep the money until a federal investigation was completed, but have preemptively reimbursed individual donors. Renacci and Rep. Betty Sutton (D) are competing in Ohio’s newly drawn 16th district.

• The four congressional campaign committees reported similar fundraising numbers in June. The National Republican Campaign Committee narrowly outraised the Democratic Congressional Campaign Committee $10.7 million to $10.5 million, while the Democratic Senatorial Campaign Committee raised $8 million to the National Republican Senatorial Campaign Committee’s $4.4 million.
