I just got a fundraising letter from the Clinton Campaign.  It started out unsurprisingly, with an ask to help retire Clinton’s campaign debt.  But then I didn’t really get what was going on in this paragraph:

Additionally to defeat Senator McCain and return the White House to the Democrats, Senator Obama will need significant resources to execute a successful campaign plan. Hillary will be doing all she can to help Senator Obama win in November and we hope you join her in this endeavor. Please let us know if you are involved in any of the upcoming DNC or Obama for America fundraising events, so we can help one another and maximize our resources.  Whether you are contributing an additional $1,000, $500, $250 or whatever you feel comfortable with, your support would be deeply appreciated.  The maximum that can be contributed towards this effort is $2,300 and that includes what you have previously contributed to Hillary Clinton for President primary fund.

First, after saying Obama will need significant resources, it doesn’t actually ask anyone to donate to Obama’s campaign, as far as I can tell.  Second, what is the point of asking people to “let them know” if they are involved in Obama or DNC fundraising events?  Does this help the Obama campaign in any way?  

I’m not suggesting anything sketchy is going on; I just really don’t understand the point of that paragraph.  Can anyone enlighten me?
