Here’s an opinion column by Inquirer columnist Isagani Cruz about where our senators’ loyalties lie.

Interestingly, those favoring the President have certain interests to pursue, like government assistance to rescue them from financial straits, security of tenure for their relatives, appointments to diplomatic posts or recommendation for an international tribunal, or plain devotion to a common background or former occupation …. The prejudgments of the senators are quite evident during the daily proceedings. The law is only secondary, the evidence of the parties immaterial and irrelevant to the final decision. The basic consideration is personal regard for President Estrada, or lack of it, regardless of the merits of the case.
