“Obama is expected to announce his VP choice in the next 24 to 36 hours and the selection won’t be unveiled by way of the usual media leak followed by a press conference. Instead, in a sign of Obama’s new model of campaigning, the digitally networked candidate plans to first announce the selection by way of early morning e-mails and text messages to his millions of online supporters and then to take advantage of a full day’s news cycle of coverage.”

“Space policy takes a higher profile as US election race moves to Florida.
With the impending retirement of the Space Shuttle in 2010, some 4,000 jobs are at stake at the Kennedy Space Center in Orlando, Florida. With its 27 electoral votes, Florida could be a deciding state in the November elections, just as it was in 2000. Other battleground states include Ohio and Virginia, where thousands of residents work at NASA’s Glenn and Langley research centres, respectively.

Obama’s policy represents a dramatic evolution for a candidate who, in statements on his website earlier this year, considered using money spent on Constellation for his education programmes. Now, his policy specifically endorses President Bush’s ‘Vision for Space Exploration’, which calls to send humans back to the Moon by 2020 as a stepping stone to the exploration of Mars.”
