General Elections 2016- battle plan?

I was just studying the 2011 electoral boundaries.
While we know that boundaries are redrawn every election, one thing I could conclude is that the PAP has everything to worry about.
Also, if the Opposition can fully get their act together, work the ground alot harder, better strategise where to send their teams etc, the gains could be significant.

If you look at the map below, the red areas are Aljunied GRC and Hougang SMC.
I've pinked out those constituencies where the Opposition came close to winning.

My advice to the Opposition is band together and form a bastion in the East. Send your A teams to take down these wards and we could have a solid Opposition base in eastern Singapore.
It's often cited that the Opposition lacks the funds and economies of scale to wage a successful fight. With this scenario, they can consolidate resources by banding these constituencies, which are all adjacent to each other, together.

Now we all know how staunchly PAP is in the West- Jurong, Choa Chu Kang, West Coast (biggest GRC by land area) and to some extent Holland-Bukit Timah.
So if the Opposition can consolidate power in the East, they can use that as a springboard to tackle these more stubborn areas.

For the PAP, they have to seriously consider:

• Who will repalce SM Goh in Marine Parade
• If Lim Swee Say can improve the performance in East Coast,  considering that he faced off with what was essentially, no disrespect, WP's 'B' team
• If they can they stretch Pasir-Ris Punggol boundaries even more to take advantage of Teo Chee Hean's safe status
• If MBT should continue in Tampines

We have a battle on our hands. Looking forward to GE 2016.

PS: Notice how tiny Tampines GRC is. Looks like the PAP had little faith in MBT.
