A new ARG (or ARRGGHHH!) poll has come out which gives more or less the same results for TX and OH that it reported last week:
TX
2/23-24
Obama 50
Clinton 42
OH
2/23-24
Obama39
Clinton 49
The last poll from 10 days ago gave Obama a six-point lead.
ARG is among the least reliable pollsters, but it's OH result is consistent with other OH results recently, and the TX poll is at least in line with its last report.
If your an Obama supporter, the thing to look for now is a confirming poll from a reputable organization like SUSA.
FWIW.
