CNET has put together a decent list of the best and worst politician-tweeters. But there is a glaring omission: SEN. CHUCK GRASSLEY.

Grassley is by far the most interesting politi-tweeter out there. This is the man who tweeted "PantsBurnLegWound" to inform followers of a freak injury. No one else can squeeze so much into 140 syllables.

In case you're wondering, here's Grassley's latest tweet:

Orrin Hatch has some thoughts about what kind of justice Obama should select.

The Utah Republican just tweeted a link to an article he published in the "Harvard Journal of Law and Public Policy." The artcle is entitled "The Constitution as the Playbook for Judicial Selection."

Chalk this one up as another way Twitter is changing the political landscape.

In addition to using Twitter as a tool to communicate interest groups' advocacy and messages, it is now also being used to dispatch memos to members of Congress and their offices over specific pieces of legislation.

Take, for instance, National Taxpayers' Union, which tweeted Monday:

NTU Vote Alert: Housing Bill Amendments: ****************************************** National Taxpayers Union Vo.. http://tinyurl.com/dmbaz5

(For the record, the vote alert is to urge the passage of two amendments that would prevent the nationalization of banks, while allowing well-capitalized firms to repay TARP funds.)

The Washington Post's Chris Cillizza (a/k/a "The Fix") has abused his Twitter privileges and the Twitter gods are cracking down on him.

The following tweet just came across his primary Twitter account, "TheFix," not to be confused with his secondary Twitter account, "thehyperfix," which he uses to tweet White House press conferences.

ARGH...Twutter [sic] has locked me out of twittering the press briefing @thehyperfix....too many tweets! CURSES.

Rep. Tim Ryan (D-Ohio) was sure to tweet out his congratulations to the man who may be his most famous constituent: NBA all-star LeBron James.

James was said Monday to be named the NBA's Most Valuable Player, leading Ryan to tweet:

Congratulations to LeBron James for receiving a well deserved MVP award.

Ryan represents Ohio's 17th congressional district, which includes Youngstown to the east and parts of Akron to the west.

It is unknown whether or not James, who continues to live in Akron, maintains his home in Ryan's district, or in the neighboring 13th congressional district, which is represented by Rep. Betty Sutton (D).

Rep. Thad McCotter (R-Mich.) takes to Twitter to defend his home state's industry:

ThadMcCotterauto workers are forgotten, and how is bankruptcy good for Chrysler and not good for Wall Street institutions? http://tinyurl.com/clvaw5

The link goes to audio of an interview with McCotter making the same case.

California gubernatorial candidate and San Francisco Mayor Gavin Newsom (D) made sure his Twitter followers in his home state knew about his appearance on east coast television this morning.

Newsom tweeted Monday:

In case you were asleep at 5 in the morning on the West Coast I was on MSNBC's Morning Joe: http://tr.im/kqt9

While on "Morning Joe," Newsom let loose a shout-out to his hundreds of thousands of followers on Twitter. Watch a video of the segment below:

Rep. Darrell Issa (R-Calif.) has turned to Twitter followers for input as to which qualities are most important in President Obama's choice for the Supreme Court vacancy.

Issa, who as a member of the House doesn't get a formal vote to confirm the president's nomination, asked followers on Sunday to name attributes that are important in a Supreme Court justice.

Issa tweeted some feedback on Monday, first:

SCOTUS feedback: @nathanmhansen no comm. clause abuse @scotteeg interprets, not makes, law @jimkrehbiel "empathy for nothing but const."

Issa also tweeted this interesting observation:

R.e. attributes of good Souter's successor: what weight do you put on legislative experience (like O'Connor in AZ)? No one mentioned this.

News broke late Thursday night and was confirmed Friday that Justice David Souter has decided to retire from the Court at the end of this term.
