Senator Antonio Trillanes IV has called for a Senate investigation into the alleged overpriced construction of the Makati City Hall “parking building.” He has most likely been instructed by his Palace and Liberal Party allies—masters?—to help in demonizing Vice-President Jejomar Binay, who is the presidential aspirant leading everyone else in opinion surveys.

A Senate hearing would give Trillanes lots of TV time for his personal promotion. But he could also end up being punished with the unwanted consequences of looking foolish and being seen by the public, including his own fans, of obviously just grandstanding.
